choose C.

首先，看问题，要找一个支持research hypothesis的一个选项。

research hypothesis强调的到底是什么？

vaccine was the source of the virus found in mesotheliomas decades later。中的来源这意思。

所以，c选项中说现在这病毒还存在在这个vaccine中，就增强了这个来源的假设了。

这个题目太ＢＴ了，我把两个帖子反反复复看了好几遍才转过弯来……

选Ｃ没错～

题目说的是在vaccine被感染的前提下，问contaminated vaccine是不是Ｍ中的病毒的来源

Ｅ说的是没被感染的vaccine，无关吧～芬兰也与美国无关吧～～

C is the answer from my point of view

Argument is focused on the point that scientists thought it is the virus in vaccine from 1960s' is the source of cancer and in choice C, it says the virus is real and this strengthen the point for sure.

In choice E says in the vaccine that had never been contaminated SV40, the virus, doesen't appeared. However, it doesn't make sense since it says the clear vaccine is clear.

I support C this time when I reviewed the question.

我昨天作prep，上面给的答案是E

同样疑惑！

A->M<-S  60%M->SV40<-V 文章说60%M就是被污染的V造成 逆否命题=原命题 没污染就没有60%M  E刚好表达了逆否命题

我亲爱的中国同学们，你们做题时真的能发现干扰选项吗？？？A----->B, since C----->A, so C----->B. What can strenthen this logic? Since "A---->B" is illustrated as a fact, so any evidence that can strenthen the first part that "C---->A" is the key. So, for this question it is really obvious that only C is the direct evidence, no matter how tedious and stupid it is, to support it.

If you cannnot understand what I write, please pass me. Good luck. 老罗说过，不要发散，一发三全对。我的伟大老师说过：
犹豫就是错。
没有为什么。


体会一下其中的深意吧。
